COMPANY CONFIDENTIAL  
PI5USB1457  
USB Charger Controller supporting  
SDP, CDP, and DCP per BC1.2 spec  
Features  
Description  
ꢀÎUSB charger controller that supports SDP, DCP and  
Notebook PCs are used around the world to charge battery-pow-  
ered handheld devices such as cell phones and MP3/MP4 players.  
Hand-held devices require communication with the notebook  
PC before they start to draw current. is ensures that the hand-  
held device will obtain sufficient current when it wants to charge.  
e issue is that the notebook PC does not have a way to provide  
this acknowledge signal to the handheld device when the note-  
book is in “Sleep” mode.  
CDP modes  
à DCP (Dedicated charger port) is used when  
enumeration is not available  
à CDP (Charging downstream port) is used when  
enumeration is available, but FAST charging is  
requested  
à SDP (Standard downstream port) is used for systems  
that can only support 500mA across Vbus  
ꢀÎSingle Power Supply, 5V 10%  
Pericom’s PI5USB1457(*/A/B) solves this issue by setting the D+/  
D- pins in the notebook PC to the required signal levels during  
“sleep” mode. When the handheld device sees these required sig-  
nal levels, it will then start to draw the current required to charge  
itself.  
ꢀÎIntegrated ESD protection up to +/- 4kV contact on pins  
2 and 3 per IEC61000-4-2 spec  
ꢀÎDetects and differentiates between mouse/keyboard (USB  
Low/Full Speed device) when in Sleep and Charge mode  
(USB1457 and USB1457A versions only)  
Cell phones within today’s market use different communication  
schemes, so the switch will need to configure itself in different  
modes. PI5USB1457 (*/A/B) can alternate between modes auto-  
matically, once device type is correctly detected.  
ꢀÎProvides multiple modes of charging to ensure all of the  
following spec's can be met:  
à USB Battery Charger 1.2 spec  
à USB Battery Charger 1.1 spec  
D+, D- and Vbus pins are protected with Pericom’s ESD protec-  
tion circuits supporting ESD damage as high as +/-4kV contact  
per IEC61000-4-2 specification.  
à USB Battery Charger 1.0 spec  
à YD/T-1591 charger spec  
à Certain modes available can also support devices using  
non-standard approaches to charging, such  
as Apple products and RIM/Blackberry products  
ꢀÎPackaging (Pb-free & Green):  
à 8-Contact TDFN, ZAE (2.0mm x 2.0mm x 0.75mm)
